原来代码，在调试不会报错，正式会报错
/** * 从文件中加载私钥 * * @param path 私钥文件名 * @return 是否成功 * @throws Exception */ public static String loadKeyByFile(String path) throws Exception { try { BufferedReader br = new BufferedReader(new FileReader(path)); String readLine = null; StringBuilder sb = new StringBuilder(); while ((readLine = br.readLine()) != null) { if (readLine.charAt(0) == ‘-‘) { continue; } else { sb.append(readLine); sb.append(‘\r‘); } } br.close(); String ret=sb.toString(); return ret; } catch (IOException e) { throw new Exception("私钥数据读取错误"); } catch (NullPointerException e) { throw new Exception("私钥输入流为空"); } } --下面调用 Resource publicResource = new ClassPathResource("cert/rsa_public_key.pem"); File publicFile=publicResource.getFile(); RSAHelper.loadKeyByFile(publicFile.getPath());
改后代码
/** * 通过文件流取文件路径 * @param source * @return * @throws Exception */ public static String loadKeyByResource(String source) throws Exception { try { Resource resource = new ClassPathResource(source); InputStream in = resource.getInputStream(); InputStreamReader isReader= new InputStreamReader(in); BufferedReader br = new BufferedReader(isReader); String readLine = null; StringBuilder sb = new StringBuilder(); while ((readLine = br.readLine()) != null) { if (readLine.charAt(0) == ‘-‘) { continue; } else { sb.append(readLine); sb.append(‘\r‘); } } br.close(); String ret=sb.toString(); return ret; // BufferedReader br = new BufferedReader(isReader); // int length = in.available(); // byte[] buffer = new byte[length]; // int len= IOUtils.read(in, buffer, 0, length); // String ret=new String(buffer); // return ret; } catch (IOException e) { throw new Exception("公、私钥数据读取错误"); } catch (NullPointerException e) { throw new Exception("公、私钥输入流为空"); } }
